I want to make an upgrade to a new graphics card but I don't know if it's compatible

So i bought a PC and I want to switch graphics card and idk if the graphics card will be compatible with the motherboard.
P.S : If you can recommend me a good and not to expensive graphics card here is my build:
Motherboard: MSI Z87-G45
Graphics Card: GTX 760 DirectCU II OC 2GB GDDR5 256 BIT
Source: Silver Power's 850W Gorilla
Processor : I5-4670k 3.40GHz

You need to post a solid number for people to work with. "not to expensive" has different meanings to different people.

Also, you'll be limited by your PSU since it looks like it's from a garbage brand. Would recommend upgrading the PSU as well.
